Perhaps this option will be interesting. In order not to order the product and not wait, you can simply buy a ready-made jewelry item with some cubic zirconia and simply exchange it for the desired gemstone. This pendant was bought in a jewelry store, and in the jewelry workshop they simply replaced the cubic zirconia with spinel. That's it! It's fast! The only thing is that you need to know the diameter of the cubic zirconia to select a gemstone of the same diameter.
